Narrow border touch display apparatus

A narrow border touch display apparatus, comprising:

• a display layer having a first surface and a second surface opposite to each other;
• a self-capacitive touch-sensing layer disposed on the first surface of the display layer and includes a touch-sensing area and a wiring area adjacent to the touch-sensing area;
• wherein the touch-sensing area is provided with a plurality of touch-sensing electrodes arranged in a matrix;
• each of the touch-sensing electrodes is connected to a lead;
• the leads extend to the wiring area,
• wherein each of the touch-sensing electrodes is jagged-shaped;
• the plurality of touch-sensing electrodes are divided into a plurality of columns;
• in each column of the touch-sensing electrodes, every three touch-sensing electrodes form a Y-axis sensing group;
• and each of the Y-axis sensing groups includes a first touch-sensing electrode, a second touch-sensing electrode, and a third touch-sensing electrode;
• wherein the first touch-sensing electrode has a first flat bottom and a plurality of downward jag portions extending downward from the first flat bottom;
• the second touch-sensing electrode has a second flat bottom and a plurality of upward jag portions extending upward from the second flat bottom;
• and the third touch-sensing electrode is positioned between the first touch-sensing electrode and the second touch-sensing electrode and has a plurality of upward jag portions and a plurality of downward jag portions;
• wherein the upward jag portions of the third touch-sensing electrode face the first touch-sensing electrode and correspond to the downward jag portions of the first touch-sensing electrode in shape;
• the downward jag portions of the third touch-sensing electrode face the second touch-sensing electrode and correspond to the upward jag portions of the second touch-sensing electrode in shape;
• and
• and a portion of the self-capacitive touch-sensing layer that is located within the wiring area extends over an edge of the display layer and is mounted on the second surface of the display layer by bending;
• and
• a flexible printed circuit board mounted on the wiring area of the self-capacitive touch-sensing layer and connected to the leads.
